Sweat equity is the most valuable equity there is.

If you have managers reporting to managers in a startup, you will fail. Once you get beyond startup, if you have managers reporting to managers, you will create politics.

I'm scared shitless of heights.

I love the competitive aspect of it [business]. It's like playing chess. Why do people play chess? Knowing the realm of moves? Even when you get to be a chess master, there are other chess masters you want to beat or outperform. And to me business is just a sport that I love to compete in; a continuous intellectual challenge that really motivates me.

The only thing in your control is effort. That's all, and that's everything.

In business, to be a success, you only have to be right once.

Even when I had nothing, I had everything. Because I love to compete.
